Over the last couple of months I've seen two Mondeo new estates (mk 4 I guess they would be). They were both a kind of midnight blue, some weird angular centre exit (IIRC) exhaust tip and badged with a red 'ST'. Big Ford badged wheels but in the style of the normal top spec Mondeo models.

But AFAIK they never made a mk4 Mondeo ST, so they could be some sort of fake one, it's just that they looked out of the box rather than some Halfrauds special, and if they were Halfrauds special how come there are two identical ones in different parts of the country.
